ROTARY WATER-MOTO R.

SPECIFICATION formingpart of Letters Patent No. 534,916, dated February26, 1895. Application filed February 9, 1894. Serial No. 499,635- (Nomodel.)

To all whom it may concern:

Be it known that I, COLUMBUS K. ROGERS, a citizen of the United States,and a resident of Salem,in the county of Essex and State ofMassachusetts, have invented new and useful Improvements in RotaryWater-Motors, of which the following, taken in connection with theaccompanying drawings, is a specification.

This invention relates to improvements in rotary water motors and it iscarried out as follows, reference being had to the accompanyingdrawings, wherein Figure 1, represents a side elevation of the improvedrotary water motor. Fig. 2, represents a cross section on the line 2-2shown in Fig.1; and Fig. 3, represents a vertical section on the line3-3 shown in Fig. 2.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

The invention consists of an inclosing shell composed of vertical sidesA A between which is secured the peripheral casing or wheel chamber Bhaving flanges b b bolted or otherwise secured to the interior of thesides A A in a water-tight manner.

In the side pieces A A are journaled the rotary wheel shafts G O towhich are secured the Wheels D D provided with wings d d d d as shown.Above the wheel chamber B is located the pressure chamber E which isseparated from the wheel chamber by a partition B which is of the formof two arcs of a circle arranged side by side upon a common base, whichshape causes the partition to closely conform to the shape of the motorwheels. The partition B is provided with two series of ejector nipplesthat project downward at a tangent to the two wheels, the nipples ofboth series being inclined in the same direction so that the wheels willbe rotated in the same direction. From the center of the partition Bdepends a divisionwall B that extends down to the motor shaft g andseparates one motor wheel from the other and prevents any,

back pressure on the blades of the wheels and also prevents any waterejected against one of the motor Wheels striking the other. The chamberE is connected by means of a pipe e to any suitable source of waterpressure.

The Water from the pressure chamber E is forced through a series ofejectors B B against the fans or wings d d of the wheels D D thuscausing the latter and their shafts to be set in a rotary motion in thedirection of arrows shown in Fig. 3.

F F are pinions secured to the respective shafts O O the teeth of whichmesh in the teeth of a spur gear G secured to a motor shaft 9 journaledin the side pieces A A as shown in the drawings by which a rotary motionis imparted to said shaft from the wheels D D in the direction of thearrows shown in Figs. 1 and 3.

To the motor shaft 9 is secured a balance wheel H and a pulley h fromwhich motion may be communicated by means of a cord or belt to themachine that is to be driven.

The rotary motion from the motor shaft g may of course be communicatedto the machine to be driven by means of gears, sprocket wheels andchains or other well known devices without departing from the essence ofmy invention.

From the lower part of the casing B leads a discharge pipe B throughwhich the water is allowed to escape from said casing after it has doneits work in causing a rotary motion to be imparted to the motor wheels.

B is a division wall between the fan wheels D D so as to prevent thewater ejected against one of the fan wheels from striking the otherwheel as shown in Fig. 3.

Each shaft 0 C may have one or more motor wheels secured to the sameshaft. In the drawings Fig. 2 I have shown two motor wheels secured toeach shaft and I wish to state that I do not wish to confine myself toany num-' ber of motor wheels on each such shaft as I may use one ormore according to the power desired to be conveyed.

By admitting water under pressure from the pipe e into the pressurechamber E the water is forced out in jets or streams through theejectors B B against the motor wheels D D thereby causing the latter tobe rotated in the direction of arrows shown and to convey a continuousrotary motion to the motor shaft g as fully shown and described.

The speed and power of the motor may easily be regulated by theadjustment of a stop cook or cutoff on the supply pipe 2, which ishowever not represented in the drawings.

ICO

Having thus fully described the nature, construction, and operation ofmy invention, I wish to secure by Letters Patent and claim- 1. In awater motor, the combination with the inclosing shell having journaledtherein two motor wheels arranged in the same horizontal plane andgeared to revolve together in the same direction, and a partitionarranged over said wheels and dividing the shell into a pressure chamberand a wheel chamber, and provided with two series of ejector nipplesprojecting downward at a tangent to said wheels, and a division walldepending from said partition between said wheels to prevent backpressure on the motor wheels, substantially as described.

2. In a water motor, the combination with the inclosing shell havingjournaled therein two shafts O, O, carrying pinions F, F, and havingrigidly mounted thereon motor wheels D,D, the motor shaft g jonrnaled inthe shell and carrying the spur-gear G meshing with the pinions C, O,and operating to cause the motor wheels to rotate together in the samedirection, the partition B arranged over said wheels and dividing theshell into a pressure chamber and a Wheel chamber and provided with twoseries of ejector nipples projecting downwardly at a tangent to saidwheels, and a division wall depending from said partition between saidwheels and extending to the shaft carrying the spur gear, substantiallyas and for the purpose specified.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 24th day of January, A.D. 189*.

COLUMBUS K. ROGERS.
